Abstract: Taking the characteristics of multi-constrained QoS (Quality of Service) routing in NGI (Next Generation Internet) into account, a unicast QoS routing algorithm based on PSO (Particle Swarm Optimization) is presented. The corresponding model and its mathematical description are introduced. With the fuzzy QoS parameters considered, such as bandwidth, delay, delay-jitter and error rate, the route with satisfied QoS is found on the basis of the proposed algorithm. Simulation and performance evaluation are conducted on several actual and virtual network topologies. The results showed that the proposed algorithm was both feasible and effective.
